Question 1.
What is resting potential?
Show hintHide hint
Think about the state when a neuron is not transmitting signals.
Question 2.
What happens during depolarization?
Show hintHide hint
Recall the influx of ions.
3Question 3.
What occurs during depolarization of a neuron?
- K+ rushes in
- Na+ rushes in
- Na+ rushes out
Show hintHide hint
Think about the flow of sodium.
4Question 4.
True or False: During repolarization, the inside of the neuron becomes more negatively charged.
- True
- False
Show hintHide hint
Remember what happens with potassium.
Question 5.
Explain how an increased concentration of potassium ions inside the neuron might affect resting potential and action potential.
Show hintHide hint
Consider how ion concentrations affect the electrical properties of the membrane.
Question 6.
Design an experiment to demonstrate the effects of inhibiting the sodium-potassium pump on nerve impulse conduction.
Show hintHide hint
Think about the essential roles of sodium and potassium in action potential generation.
